Inventor: NAKAJIMA KUNIHIRO
IPC: B61D27/00
Filed: 1990-11-26
Abstract: PURPOSE:To inhibit the pressure of coolant on the high pressure side of refrigerating cycle when a railway vehicle enters into a tunnel, by changing the rotational speed of a motor for an outboard fan into a value which is higher than that during running outside the tunnel, in accordance with a signal delivered from a detector for detecting an abrupt variation in the atmospheric pressure. CONSTITUTION:A detector 8 detects an abrupt variation in the atmospheric pressure which occurs when a railway vehicle enters into of exits from a tunnel, and a control circuit 9 delivers a rotational speed change-over signal for changing over the a.c. frequency into a value which is higher than a specified drive frequency during running, to an inverter 7 in accordance with a detection signal from the detector 8. As a result, the rotational speed of a motor 6 for an outboard fan 5 is changed over into a higher value so as to increase the air volume of the outboard fan 5 so that the air volume during running in the tunnel is larger than during running outside the tunnel, that is, a satisfactory air volume can be ensured. Further, in a condenser 2, the condensation of coolant gas at a high temperature and at a high pressure does not lower, and accordingly, it is possible to restrain the pressure of the coolant gas on the high pressure side from increasing.

Title: Precision cutter by radical reaction
Inventor: HAMADA SHUJI
IPC: H01L21/301
Filed: 1992-12-01
Abstract: PURPOSE:To precisely cut a thick element by uniformly supplying reaction gas to the bottom of a groove. CONSTITUTION:A reaction gas supply nozzle 23 is arranged in parallel with a wire electrode W on the electrode W to be fed in a longitudinal direction. The nozzle 23 is formed thinner than a cut groove 24a formed on an element 24 to be cut by radical reaction, and provided at its lower edge with a slitlike injection port. The element 24 to be cut is oscillatorily vibrated together with a support member 25 via a ball screw 65 and a nut 66 by normal and reverse rotations of a motor 64 in a longitudinal direction of the electrode W. The nozzle 23 is introduced into the groove 24a as the cutting is advanced together with the electrode W to supply the gas to the bottom 24b of the groove. A flow of the gas is deflected as the element to be cut is vibrated by the vibration of the element 24 to the nozzle, and the gas is supplied uniformly and effectively to the bottom of the groove. Thus, even if the element 24 to be cut is thick, it can be cut without failure.

IPC: H01M10/0569
Filed: 1987-12-18
Abstract: PURPOSE:To retard increase in electrode potential in charging and to retain the reliability and performance of a battery by using a specified compound as a solvent of an electrolyte in a secondary battery in which a conductive polymer is used in at least one electrode. CONSTITUTION:1,2-butylene carbonate and sulfolane as shown in the chemical formulas are mixed in the volume ratio of 9:1-1:4 and used as the solvent of an electrolyte.

By this constitution, the solvation ot sulfolane with an anon such as perchlorate ion used as a dopant is easily dissolved by the interaction of sulfolane and conductive polymer and an increase in voltage in charging is retarded. Since the decomposition voltage of this mixed solvent is high, the corrosion of a battery container and the decomposition of the conductive polymer are retarded and the performance of a battery is kept high.

IPC: G11C11/401
Filed: 1988-12-20
Abstract: PURPOSE:To enable a sense amplifier to be arranged in spite of the interval of bit lines by arranging a pair of bit lines connected to the sense amplifier being arranged in a direction extending to the pair of bit lines by crossing with another sense amplifier existing at a memory cell array area side observing from the sense amplifier. CONSTITUTION:Plural sense amplifiers SA are arranged so as to be aligned along a direction where the bit lines BL and the inverse of BL are extending. And, for example, the bit lines BL1 and the inverse of BL1 connected to the sense amplifier SA1 are arranged so as to cross with the sense amplifiers SA2-SA4 not being connected to the bit lines BL1 and the inverse of BL1. In other words, one sense amplifier circuit SA is formed so as to straddle over the plural pairs of bit lines BL and the inverse of BL. Therefore, it is not required to arrange the sense amplifier corresponding to each pair of bit lines or the interval of the bit lines BL and the inverse of BL. In such a way, it is possible to design the layout of the sense amplifier in spite of the interval of the bit lines BL and the inverse of BL.

Title: Synchronizing system in word interleave system
Inventor: TAKADA TADAYUKI
IPC: H04J3/06
Filed: 1990-11-27
Abstract: PURPOSE:To quicken the synchronization, and also, to avoid the malfunction by outputting a detecting signal without taking a synchronizing protection in a frame synchronization word detecting circuit, and controlling a bit shift for generating a window by a majority decision of these detecting signals. CONSTITUTION:A majority decision of outputs SYNC1-(n) of a frame synchronization word detecting circuit 22 of a lower order group signal is taken by a majority deciding circuit 12f. In the frame synchronization word detecting circuit 22, the synchronizating protection is not taken, and when a frame synchronization word is detected even once, an output SYNC is generated immediately (SYNC is set to H). In the majority deciding circuit 12f, when the number of those of H is larger than the number of those of L in the SYNC1-(n), an output for inhibiting a gate 12c is generated, and a bit shift is stopped. In such a way, a quick synchronization can be executed, and also, a fear of a malfunction is eliminated without executing the synchronizing protection.
